Note: Brightside® Polyurethane must be sanded between coats.
PREVIOUSLY PAINTED SURFACES: The surface must be clean and dry. Sand with 220-320 grade (grit) paper. Remove sanding residue.
BARE FIBERGLASS: In Good Condition Begin by scrubbing well using soap and water and a stiff brush. Rinse with fresh water. Remove wax and other contaminants using either Fiberglass Solvent Wash 202 or Fiberglass Surface Prep YMA601V. Sand with 220-320 grade (grit) paper. Remove sanding residue. In Poor Condition Clean as above. Sand with 80 grade (grit) paper. Apply Pre-Kote.
CLEAR EPOXY: After the epoxy has cured, remove any amine blush by scrubbing well using soap and water, and a stiff brush, or by using Fiberglass Surface Prep YMA601V. Rinse with fresh water and allow to dry. Sand with 80 grade (grit) paper. Remove sanding residue. Apply one coat of Epoxy Primekote 404/414.
BARE WOOD: Sand surface with 180-220 grade (grit) paper, wipe clean. Apply Pre-Kote. Sand surface with 220 grade (grit) paper, wipe clean.
BARE METAL: Sandblast or grind, remove sanding residue. Immediately apply Interprotect 2000E thinned 15% with Interlux Solvent 2316N. When the Interprotect is thumb-print tacky apply one coat of Epoxy Primekote 404/414. Sand with 220 grade (grit) paper. Remove sanding residue.
APPLICATION INFORMATION: Apply 2-3 coats of Brightside® Polyurethane following the proper dry times. Sand between coats using 220-320 grade (grit) paper. Remove sanding residue. Brightside® may be applied by roller and brush using the roll and tip method. Thin if necessary with Brushing Liquid 333 to improve brushing characteristics. It is best to paint on warm, dry mornings. Cold weather retards the drying and humidity can spoil the gloss. Airless Spray Pressure: 170 bar/2500 psi. Tip Size: 0.33-0.41 mm/13-16 thou. Conventional Spray Pressure Pot: Pressure: 3.44-4.47 bar/50-65 psi (gun pressure); 8-10 psi (pot pressure). Tip Size: 0.89-1.4 mm/35-50 thou. Siphon Cup: Pressure: 3.44-4.47 bar/50-65 psi - gun pressure. Tip Size: 1.5-1.8 mm/60-70 thou. Other When spraying Brightside® Polyurethane be sure to follow dry times. Do not apply tack or mist coats. Apply only one coat per day. Spray pressures listed are recommendations only. The applicator may use any settings which yield the best results for the individual spraying technique and current weather conditions. Brightside® Polyurethane is best applied in thin coats. Do not apply heavy coats as this will affect dry through. Failure to follow proper dry times carefully will cause improper drying, wrinkling and loss of adhesion. Avoid painting in direct sunlight. Product temperature should be minimum 10°C/50° F and maximum 29°C/85°F. Ambient temperature should be minimum 10°C/50°F and maximum 35°C/95°F. Substrate temperature should be minimum 10°C/50°F and maximum 29°C/85°F. Surface must be dry and clean, and free from grease, detaching paint etc. Be sure to use Epoxy Barrier-Kote 404/414 over clear epoxy to prevent blush from affecting drying and adhesion of Brightside® Polyurethane.

I have been using Brightside on my Allied Seabreeze 35 for 15 years on the decks and bootstripe with very good results.

I am not a professional boat painter but a very capable do it yourselfer, having built and painted three boats and restored a fourth. I am currently restoring a finned fiberglassic(1959 Glass Craft Imperial) when the West Marine manager told me about Interlux Brightsides, saying you could roll and tip it, probably 3 coats and not have to wet sand, compound and polish and end up with a finish that looked like it had been sprayed professionally...Who wouldn't be intrigued...I just completed my 10th coat sanding with 320 between coats as the label instructs. Started with one quart of their Interlux Pre-coat, one quart of their 333 thinner and two quarts of their red Interlux Brightsides. So far I've actually used 5 1/2 quarts paint and I also had to buy a second quart of primer and 333 brushing thinner. I've talked with Interlux reps twice by phone thinking I just wasn't doing things correctly ass I just wasn't getting that sprayed on look no matter how much I thinned the paint. If I thinned it right so it leveled out nicely on the bow than it would run and sag badly on the vertical areas like the fins and splash well, this would be okay if I could just sand and repain the area with runs and then wet sand compound and polish everything to blend it all in...but I can't. Brightsides is not supposed to be sanded or polished at all after last coat, technician said it ruins the gloss, uv protection and life of the product. I am very disappointed that I purchased 5 1/2 quarts of this product' (three from you) thinking I just had to get the hang of it, in talking to the technicians I explained I am painting in my heated (70 degrees) where weather and humidity are not a factor, also when I thin it down so It really levels out I see the sanding scratch marks right through the paint! If a person really wanted (show quality) I would strongly recommend against this product and recommend a paint that could be compounded and polished. I just want my money back or I want you to send me some paint that I can wet sand, compound and polish to a great finish. Even the last tech I talked to suggested I thin it significantly more and do three or more coat without sanding between coats and repainting before previous coat has dried. That may work but it is exactly counter to everything on their website and I wasn't about to buy any more of this.
Very good paint

This is the first boat I have designed and built. I chose Interlux so I would have the ability to buy paint in any port. I found it to be very good. If you prep properly, the pain looks like it was sprayed on. Well, at least mine does. Don't overdo the brushing liquid. I found that for the first coat you don't need the brushing liquid. Sand that then add 2 percent and do the second coat. For the third coat add 4 percent. That is what I found that works in Florida. Up north it is probably more.
